Lua 将侦听器添加到Corona APK中的图像

我在CoronaLabs Studio中创建了一个新项目，其中包含了

基于物理的游戏

开始选项，以及作为初学者加载的所有内容。我不知道应该将

addEventListener（）

放在哪里，这样我就可以使该框可点击或点击后被销毁？ 我尝试了一系列不同的方法，将这行代码放在脚本中，以使框可单击

virus:applylinearpulse（0，-0.25，virus.x，virus.y）

下面是

level1.lua

脚本

在这种情况下，我有

require("toast")
local composer = require( "composer" )
local scene = composer.newScene()

-- include Corona's "physics" library
local physics = require("physics")


--------------------------------------------
tapCount = 0
tapText = display.newText( tapCount, display.contentCenterX, 20, native.systemFont, 40 )

--------------------------------------------

local screenW, screenH, halfW = display.actualContentWidth, display.actualContentHeight, display.contentCenterX

function scene:create( event )

    -- Called when the scene's view does not exist.
    -- INSERT code here to initialize the scene e.g. add display objects to 'sceneGroup', add touch listeners, etc.


    local sceneGroup = self.view

    physics.start()
    physics.pause()

    local background = display.newImageRect("game-background.png", 1170, 658)
    background.x = display.contentCenterX
    background.y = display.contentCenterY

    -- OFFSCREEN BOX, position it, and rotate slightly
    local box = display.newImageRect( "box.png", 40, 40 )
    box.x, box.y = 160, -100
    box.rotation = 33
    -- add physics
    physics.addBody( box, { density=1.0, friction=0.3, bounce=0.2 } )

    -- create a grass object and add physics (with custom shape)
    local grass = display.newImageRect( "grass.png", screenW, 82 )
    grass.anchorX = 0
    grass.anchorY = 1
    --  draw the grass at the very bottom of the screen
    grass.x, grass.y = display.screenOriginX, display.actualContentHeight + display.screenOriginY

    local grassShape = { -halfW,-34, halfW,-34, halfW,34, -halfW,34 }
    physics.addBody( grass, "static", { friction=0.3, shape=grassShape } )

    sceneGroup:insert( background )
    sceneGroup:insert( grass )
    sceneGroup:insert( box )
end


function scene:show( event )
    local sceneGroup = self.view
    local phase = event.phase

    if phase == "will" then
        -- Called when the scene is still off-screen and is about to move on screen
    elseif phase == "did" then
        -- Called when the scene is now on-screen
        physics.start()
    end
end

function scene:hide( event )
    local sceneGroup = self.view

    local phase = event.phase

    if event.phase == "will" then
        -- Called when the scene is on-screen and is about to move off-screen
        physics.stop()
    elseif phase == "did" then
        -- Called when the scene is now off-screen
    end

end

function scene:destroy( event )
    -- Called prior to the removal of scene's "view" (sceneGroup)
    local sceneGroup = self.view

    package.loaded[physics] = nil
    physics = nil
end

---------------------------------------------------------------------------------

-- Listener setup
scene:addEventListener( "create", scene )
scene:addEventListener( "show", scene )
scene:addEventListener( "hide", scene )
scene:addEventListener( "destroy", scene )

-----------------------------------------------------------------------------------------

return scene

如果我正确理解了您的问题，下面是一个示例，您可以单击一个框并销毁它

function scene:create(event)

 local function destroyMe(event)
    display.remove(event.target)
    event.target=nil
  end

 local box = display.newImageRect( "box.png", 40, 40 )
    box.x, box.y = 160, 100
    box.rotation = 33
    -- add physics
    physics.addBody( box, { density=1.0, friction=0.3, bounce=0.2 } )

  box:addEventListener("tap",destroyMe)

end

如果您使用的是

touch

event，那么

event

将分为三个阶段。因此要小心
